Service will not start

[Lawrence Pepper]

Hello,

I have been running MYSQL on a windows server 2008 r2 box for a couple years now, no problems. All of a sudden yesterday after a restart of the server the MYSQL service will no longer start. I get the following error:

130813 10:27:48 [Note] Plugin 'FEDERATED' is disabled.

I can not figure out the problem. PLEASE HELP!
